Well , they must have put out the ban hammer. On my server azshara, pyrite ore was regularly under 60g a stack and elementium ore was always under 40g a stack...well no more...until the bot hacks figure out the latest patch.
Pyrite ore ever got down to .99g each at one point.
I stocked up and am now going through my stockpiles milling and prospecting.
I am seeing cut inferno rubies go from 120g to 180g.
Are you also seeing the bot farmer mats gone off your auction house?
